NiceZyme View of ENZYME: EC 2.6.1.81

Accepted Name
Succinylornithine transaminase.
Alternative Name(s)
N(2)-succinylornithine 5-aminotransferase.
SOAT.
Succinylornithine aminotransferase.
Reaction catalysed
N(2)-succinyl-L-ornithine + 2-oxoglutarate <=> N-succinyl-L-glutamate 5-semialdehyde + L-glutamate
Cofactor(s)
Pyridoxal 5'-phosphate.
Comment(s)
  • Also acts on N(2)-acetyl-L-ornithine and L-ornithine, but more slowly.
  • In Pseudomonas aeruginosa, the arginine-inducible succinylornithine transaminase, EC 2.6.1.11 and EC 2.6.1.13 activities are catalyzed by the same enzyme, but this is not the case in all species.
  • This is the third enzyme in the arginine succinyltransferase (AST) pathway for the catabolism of arginine.
  • This pathway converts the carbon skeleton of arginine into glutamate, with the concomitant production of ammonia and conversion of succinyl-CoA into succinate and CoA.
  • The five enzymes involved in this pathway are EC 2.3.1.109, EC 3.5.3.23, EC 2.6.1.81, EC 1.2.1.71 and EC 3.5.1.96.
